Specification of Letters Patent.

Patented Dec. 17, 1907.

Application filed January 14,1907. Serial No. 352.202.

To all whom it may concern:

Be it known that I, LIASOHIL VERSE, a citizen of the United. States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Closures for Jars, Bottles, and Like Receptacles, of which the following is a specification.

My invention relates to metallic closures for bottles, jars, and other like receptacles, and more definitely to that class of such articles composed of more than one piece of metal, and designed to be applied on the mouth of the receptacle under exterior mechanically applied downward pressure, while a holding member is also by mechanical means and at the same time turned under the shoulder of the neck of the receptacle in sealing.

The objects of my invention are to provide an effective, neat appearing and inexpensive closure of this type, that may be mechanically applied expeditiously and with safety and certainty, and that may readily be unsealed without the use of a key or other implement; a further and special object being to rovide a closure which may be manually sufficiently well replaced upon the receptacle to serve against spilling of its contents while being intermittingly dispensed, by moderately re-sealing the same, or optionally so that a separably fitted outer cup or shell, forming part of my invention, may alone be used as a simple lid or cover for the unsealed recedptacle and the inner cap or shell discar ed.

My invention in preferred form comprises two cup-shaped parts, one within the other,

the inner and deeper one having its depending and, preferably, slightly flaring flange divided vertically in a plurality of places entirely from bottom to top, and made of thin nonresilient, readily bendable metal sufliciently ductile to permit of its lower edge being turned by mechanical appliance under the shoulder of the neck of the receptacle in sealing the same the outer cup being separably fitted over the inner one and preferably having a non-flaring, straight, or nearly straight, and solid circumferentially continuous, de ending flange considerably shorter than tlie flange of the inner cap, serving, first, to keep the divided sections of the inner cap from disengagement radi- D. CoN- ally with the shoulder after they have been mechanically applied to the same, and, secondly, serving either to perform a like service,. on manual returning of the entire closure to the mouth of the receptacle for temporary closure thereof, or, after discarding the inner cup, to be used alone as a lid or cover only. therefor, after first unsealing.

My invention further comprises other advantageous features in structural form, all which are hereinafter fully set forth and definitely claimed.

In the drawings: Figure 1 is a plan or top view of the outer shell or cup. Fig. 2 a crosssectional elevation of the same. Fig. 3 is a side elevation, partly sectional, of the inner cup or shell, and Fig. 4 an edge view of the disk of cork or other suitable sealing medium. Fig. 5 shows my invention assembled and upon the mouth of a bottle in position for being by mechanical means secured thereto. Fig. 6 is an internal view of the inner shell. Fig. 7, partly sectional, shows my invention complete as it appears after having been mechanically secured on the bottle in. sealing the same, and also shows in part the method of manual removal or unsealing. Fig. 8 further shows the method of and action in manually unsealing. Figs. 9 and 10 are respectively a partly sectional elevation and a plan view s owing two modifications of form of the outer cup or shell, one thereof for facilitating its removal, and the other to economize material, all which will now be more fully described in detail.

Like letters indicate corresponding parts throughout the several figures,

A is the outer shell, and a an external. annular bead at the margin on its top, but

which may be dispensed with, as its use is chiefly for ornamentation.

vB, is the inner shell, which is preferably made slightly flaring, and of quite thin and fairly ductile metal, the depending flange being divided or slit vertically the entire depth thereof, at b b, in a number of places, more or less, according to the diameter of the cap; those for use on small mouthed receptacles requiring fewer slits than larger ones. C, is a disk of cork or other suitable sealing medium, inclosed in this inner shell (see Figs. 5, 7, 8 and 9).

5 Figs. 7, 8 and 9, shows the depending flange of the inner shell as it appears when bent under the shoulder, d of the top, d, of the bottle, D, in sealing of the latter.

(L in Figs. 9 and 10, shows a modified form of the outer shell, A, that may be employed consisting of a row of external, radially projecting semi-spherical beads, preferably at or near the upper margin of the shell, to facilitate removal of this shell, as will hereinafter be shown.

Fig. 10 shows also another modification consisting of the cutting out of a disk K from the top of the outer shell, A, making an opening from a to a, as shown, especially practicable in the larger sizes of closures used on wide mouthed receptacles, because from the disk K so cut out shells for smaller closures may be drawn, or stamped. It will be seen that thus opening the top of the outer shell still leaves an inwardly extended flange, shown at a, Fig. 10, for engagement with the peripheral marign of the top of shell B.

It will readily be seen by, those skilled in the art that my improved closure can be manufactured economically and with great facility.

The operation of my invention is as follows: As a finished product, made as described, and assembled as shown in Fig. 5, it is, with a disk of sealing medium inclosed, placed upon the top of a receptacle to be sealed, and by well known mechanical devices applied to the exterior surface of the top of the outer cap, pressed down upon the same very firmly to the position shown in this figure; then, while so under pressure, the lower depending edge, 5 (Fig. 7), of the inner shell only is, also by mechanical means securely bent under the annular shoulder of the receptacle, thus sealing the same, the depending but shorter continuous flange of the outer shell, at its lowest margin, by snugly embracing the sections of the flange of the inner cap at a circumferential line ust at or slightly above the bend line of the underturned part, b effectually keeps the latter from disengagement with the shoulder (1 during and after such mechanical application. To open or unseal a receptacle so sealed, with my improved closure, place the thumb against one side, as in Fig. 7, and press forcibly against the outer shell, which latter, having greater diameter at the top inside than the external diameter of the top of the inner shell, (a feature of my present invention) is in consequence and by this means readily pushed over slightly. It is then pushed in like manner from the opposite side, when it will be found to be loosened and quite easily removable.

If the beaded (0, a construction shown in Figs. 9 and 10, or any similar circumferentially extended undulated or roughened exterior is employed, then the shell, A, may be removed by grasping it firmly with the hand,

these beads, or their equivalent, affording a good grip thereon, but the before defined differing diameters of the caps or shells at their tops should be employed. Now, the outer shell having beenremoved, the sections of the slitted flange of the inner shell may successively be pried out from under the shoulder of the bottle by the thumb or finger nail with ease, safety and facility, as shown in Fig. 8, because, first, the slits, b I), extend entirely to the horizontal plane of the interior surface of the top and, secondly, because the metal being thin and ductile readily bends at the point 6 across the top of the shell in a straight line from the upper terminals of adjacent slits, so that no implement is required in this unsealing.

If the contents of the receptacle are to be intermittently used, then the closure may be manually replaced entire, and sufficiently well to prevent spilling. If only a lid or cover is desired, then the outer shell only is used, the inner one being discarded, except in case of the modification where the top of this outer shell may be cut out, when it would not so serve.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. In a metallic closure of the class described, in combination, an inner cap, adapted to inclose a disk-shaped sealing medium and to be applied to receptacles as set forth, having a non-resilient ductile dependent flange plurally divided its entire depth, and an outer separably fitted removable cap, inclosing the former, of greater interior diameter at its top than the external diameter of the top of the inclosed cap and in circumfer ential engagement at its lower edge with the flange sections of the latter just above the lower edges thereof.

2. In a metallic closure of the class described, in combination, an inner cap, adapted to inclose a disk-shaped sealing medium and to be applied to receptacles as set forth, having a non-resilient ductile dependent flaring flange plurally divided its entire depth and an outer separably fitted removable cap, inclosing the former, of greater interior diameter at its top than the external diameter of the top of the inclosed cap and in circumferential engagement at its lower edge with the flange sections of the latter just above the lower edge thereof.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
